Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cable detection robots are limited by their fixed structures, which make them unsuitable for navigating diverse cable diameters and obstacles like cable clamps, leading to inefficient and potentially hazardous manual detection methods on suspension bridges.
Innovation Solution
A cable detection robot with a rotatable mechanism and adjustable holding apparatus, driven by servo motors, allowing it to adapt to different cable diameters and navigate obstacles by adjusting the positions of its main bodies and using a multifunctional detection frame and obstacle surmounting camera apparatus for stability and precision.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a fixed and closed wheeled clamping structure is used, then the robot can maintain stable movement on cables with unchanged cross sections, but it cannot adapt to cables with different diameters or cross obstacles such as cable clamps
Solution Approach 1:
The patent applies the dynamics principle by transforming the fixed clamping structure into a dynamic, adjustable one. The holding apparatus incorporates a first servo motor that can rotate to adjust the clamping angle, and a rotatable mechanism that allows the robot to change its orientation. This enables the robot to adapt to cables of different diameters and to surmount obstacles like cable clamps while maintaining stable movement during normal operation.
Solution Approach 2:
The patent segments the robot into multiple functional modules: a first main body, a second main body, a rotatable mechanism connecting them, and a holding apparatus with adjustable components. This segmentation allows each module to perform specific functions independently, enabling the robot to adjust its configuration for different cable diameters and obstacle conditions while maintaining overall structural stability.
2Reliability
If manual detection methods are used with hoisting machines or hydraulic elevating platforms, then cable detection can be performed, but the construction period is long, costs are high, and worker safety is compromised due to extreme working environments
Solution Approach 1:
The patent applies the self-service principle by designing an autonomous robot that performs cable detection without human intervention. The robot is equipped with its own driving apparatus (driving motor and wheel), holding apparatus with servo motors for autonomous adjustment, and detection devices. This eliminates the need for manual operations using hoisting machines or hydraulic platforms, ensuring worker safety while reducing construction time and costs.
Solution Approach 2:
The patent replaces complex mechanical systems (hoisting machines, hydraulic elevating platforms) with a self-contained robotic system that uses integrated driving motors, servo motors, and rotatable mechanisms. This substitution eliminates the need for external support equipment, significantly reducing construction period and costs while improving worker safety by removing humans from extreme environments.
3Device complexity
If the holding apparatus uses a fixed clamping structure, then the device complexity is reduced, but the robot cannot adjust to cables with different diameters
Solution Approach 1:
The patent applies the universality principle by designing a holding apparatus that can perform multiple functions: clamping cables of different diameters, adjusting to different angles, and surmounting obstacles. The first servo motor enables angle adjustment for different cable diameters, while the rotatable mechanism provides obstacle-surmounting capability. This multi-functional design maintains reasonable structural simplicity while achieving high adaptability.
